Trevorski, Traveling Wanderer

Whenever a Token creature enters the battlefield under your control, put a +1/+1 counter on a target creature you control.
At the beginning of your end step, you may search your library for a creature card that has a converted mana cost less than or equal to the number of +1/+1 counters on Trevorski, Traveling Wanderer and then, reveal it and put it into your hand.
